Looking for a sidebar widget with rotating images/links

I’m a writer and what I’d like to have is a widget on the sidebar that will randomly showcase a cover image from one of my books (maybe with a pull-quote from the book) and visitors can then click on that image and it will take them to a post dedicated to the book. The Buy This Book plugin is kind of what I’m talking about, although they don’t include all the links I want in their app (and I can’t categorize the book pages into a series, which I can do with regular posts).
